Proven Performance
These carburetors have the same great features as our proven and dependable Performer Series line such as: float levels set at the factory so adjustments are rarely needed for "bolt on and run" performance; 2-step metering rods for independent tuning of cruise and power circuits; change jets, adjust floats or replace needles and seats without draining fuel.
